Patent GB-726007-A (GB)
Title: Methods of and apparatus for extruding lead and lead alloys
IPC: B21C23/30
Filed: 1953-04-24
Abstract: 726,007. Extruding. WESTERN ELECTRIC CO., Inc. April 24, 1953 [April 30, 1952], No. 11354/53. Class 83 (4). In the extrusion of lead or lead alloy, any leakage lead is prevented from reaching the bearings or other vital parts of the extrusion apparatus by introducing into the latter a fluid which contacts the leakage lead and causes it to fragment by rendering it brittle or by producing a chemical change. The fragmented material passes from the apparatus with the exhaust fluid. An apparatus for lead-sheathing electrical cables has a screw impeller 10 with helical threads 12 which force the molten lead or lead alloy from an inlet 48 to an extrusion die. The impeller is rotatably mounted in bearings 25, 26 and is supported by bushings 18, 20. Leakage lead passing backwards between the bush 18 and the impeller reaches an annular chamber 37 to which compressed air is supplied through a duct 40. This air causes rapid oxidization of the lead and the powdered lead oxide thus formed is blown out of the apparatus with the air through radial ducts 38. A filter (not shown) is provided to prevent the lead oxide from polluting the atmosphere. Instead of compressed air, oil may be used which causes the lead to become brittle and crusty, the lead residue is flushed out with the oil and the latter is filtered and re-circulated through the apparatus. Sealing grooves 54 and a labyrinth packing 28 are also provided on the impeller. Lubricant is supplied to the bearings through a duct 30.
